Adjuvant pitolisant in a case with early-onset schizophrenia

<p><strong>Objectives:</strong> Early-onset schizophrenia is notorious for poor prognostication and treatment refractoriness. Child/adolescent psychiatric population, by virtue of age, is at a heightened risk for cardiometabolic risk of atypical antipsychotics. Available pharmacological options are, sorely, too limited to mitigate this risk.</p> <p><strong>Methods:</strong> The authors are reporting here on an adolescent case with early-onset schizophrenia who has favorably responded to olanzapine but with problematic weight gain that failed a trial of add-on metformin. A trial of add-on pitolisant was pursued.</p> <p><strong>Results: </strong>Adjunctive pitolisant has successfully helped with the weight issue. Strikingly, there were parallel improvements in both cognitive and negative domains as well.</p> <p><strong>Conclusions:</strong>Add-on pitolisant can be a safe and effective strategy to address antipsychotic-induced metabolic syndrome. Gains might also span negative/cognitive domains. This might open new treatment venues for such complicated clinical scenarios that await replication in larger rigorous studies.</p>
